To the under face of each as at lo, for the reception between it and the draft timber A, a box or casting C, constitutsill, of a ange Z projecting from a chating 9o 4o ing, in effect,a draft iron, is secured by means plate m on the front of the sill.

of suitable bolts a, each box or casting being Between the forward ends of the top and made approximately cylindrical in cross secbottom plates of the castings C, C, comparatiou,a-t"points intermediate of its ends, as at tively thin webs n are made, each web being l19,/ withvthe inner wall removed for the accommade with perforated enlargements o o2 for 95 ,45` modation of cups or boxes D made integral the passage of bolts n n2 the bolts n passing with the draw-bar E, saidcups or boxes D bethrough said top and bottom plates and the ing of -an external contour corresponding sill B and the bolt n2 passing through these with the internal contour of the interior of parts and also through the iiange vZof the the cylindrical portion of the fixed castings @hating plate and the strap or bracket F. roo 5o C and adapted to have a sliding movement At the junction of the forward end of the therein, as hereinafter more fully explained. top plate c and the cylindrical portion b of each casting C, an upturned lug or iiange p is made and adapted to project behind the sill B.

Between the ends of the portion l) of each casting C, a hollow lugq is made and adapted to enter recesses in the draft timbers A.

The cups or boxes D project from each side of the draw-bar E, and in each cup a stout spring G is located, the inner ends of said springs bearing against the partition walls r which divide the cups D and at their outer ends against the end walls s of the cylindrical portions b of the castings C. The inner edges of these springs are protected by Iiangest projecting from the rear end of the draw bar E. To provide abutments for the draw-bar when the same Vibrates laterally, flanges tt are made on the forward enlargements 02 of the webs n as shown in Fig. 1.

Instead of arranging the springs G, G, at the side of the draw-bar as above described, said springs may be arranged above and below said drawbar as Shown in Figs. 5, G and 7. In this form of the invention the drawbar is provided with integral cups or pockets l, 2, above and below the same for the reception of the springs G G. One end of the upper spring G bears against the bottom or end of the box or pocket l and the other end bears against a plate 3 secured to the end sill B. The box or pocket 2 entersa box or pocket 4 made integral with and between draft irons 5, which latter are secured to the draft timbers of the car, the box or pocket t being of such length relative to the box 2, as to permit a longitudinal movement of the latter. The lower spring G bears at one end against the bottom or end of the box or pocket 2 and at the other end against one end of the box or pocket 4t. A bufng spring 6 is adapted to bear at its forward end against the rear end of the draw-barand at its rearend against a transverse bar 7 located on an intermediate plate 8 iliade integral with the draft irons 5, said plate also serving to support the buling spring 6.

In the form of the invention shown in Fig. 9, the lower spring G and the draft irons -above referred to are dispensed with. The bufting spring G is retained in this construction and supported by a plate 6*"L secured to the draft timbers, the draw-bar and draw-head being supported by plates or straps 9 and lO secured respectively to the end sill and draft timbers.

In Fig. 9, the draw-bar is provided with a single integral box or pocket ll (corresponding to box or pocket l in Figs. 5, 6 and 7) located on the top of said draw-bar, the spring G being located in said box or pocket and bearin g against the end of said box or pocket and the plate 3 secured to the end sill.
